T 0 all whom it may concern Be it known that 1, WILLIAM STENDER, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Bottle- Feeding Mechanism for Annealing Ovens; and I do hereby declare that the following is a full, clear, and exact description thereof.

This invention relates to new and useful improvements in bottle feeding mechanism, and more particularly to a mechanism adapted to convey the bottles from the protect the bottles from sudden or unequal cooling duringtheir travel from the molder to the oven.

A still further object of the invention is to provide improved means for timing the delivery of the bottles from the conveyor to the bed of the oven.

One practical embodiment of the invention is illustrated I in the accompanying drawings, in which- Figure 1 is a plan View of the device with a portion of the oven cut away so as to show the mechanism inside.

Figure 2 is a detailed sectional view on the line 22 of Figure 1.

'Figure 3 is a detailed sectional view on the line 33 of Figure 1.

Flgure i is a vertical sectional view on the line 4-4 of Figure 1.

Figure 5 is a side elevation of the mechanism which conveys the bottles away from the molder.

Figure 6 is a vertical cross sectional view on the line 66 of Figure 5, and

Figure 7 is a detailed view of one of the links of the conveyor.

The mechanism of which my invention forms a part, comprises a conveyor A, which receives the bottles B from the molder. The bottles are transferred from this conveyor to the conveyor C, which, in turn, delivers the bottles to the conveyor 1) which carries them into the oven E. The conveyor A is made up of a series of links 10', which are connected together to form an endless belt, the links having laterally projecting rollers 11 which travel in the guideways 12 formed in the opposing sides of the conveyor frames 13 and 1 1. Each link comprises a flat surface of insulating material 15, preferably asbestos, and beneath this asbestos openings 16 are provided. Across the underside of the links a series of teeth 17 are formed, and the teeth of all the links together form a continuous series throughout the length of the belt.

A spur gear 18 is in driving connection with the teeth 17, and this gear is rotated by the shaft 19 through the worm gearing 20 from the shaft 21 which may be connected with any desired source of power. It will also be noted that the gear 18 is in mesh with the lower return lap of the conveyor as shown at 22 in Figure 6, thus both the forwardly moving and the return laps of the conveyor are positively driven. The bottles are delivered by the conveyor A into the chute 23 by the inwardly converging arms 24 and 25. They are then carried by the transfer wheel 26 to the conveyor C.

The transfer Wheel 26 is mounted on the vertical shaft 27 which is driven through the friction gearing 28 from the shaft 29 which is driven by the worm gearing 30 from the shaft 19.

As the transfer wheel 26 engages the bottles the teeth 26 will be forced between them to separate them so that when they are received by the conveyor C they will be spaced apart.

The bottles are now delivered between the converging arms 31 to the conve or D, which travels in a horizontal plane t rough the annealing oven. The conveyor D comprises a plurality of links, each of which carries a projecting tooth 32 which engages a bottle and carries it around the passageway 33 into the oven. The conveyor D is carried by the sprocket wheels 34 and 35 mounted on the vertical shafts 36 and 37 respectively, a tensioning device 38 being provided for adjusting the tension of the chain. The shaft 36 is driven by the worm gearing 39 from any suitable source of power.

The upper end of the shaft 36 has. a' gear 40 secured thereto which meshes with the gear 41 mounted on the stub shaft 42 The gear 41 carries a finger 43 which, as it rotates, engages a cam at to rock the shaft 45 which extends transversely through the oven and is mounted in the bearing brackets 46. The pusher 4:? which is mounted on the shaft a5 is thus moved transversely of the. conveyor to shove the bottles quickly out of the teeth 32 so that they will be carried by the movable bed without being disarranged.

When the cam 44 has been released by the fin 'er as, the pusher is returned to its norma position by the spring as which acts against the arm 48 carried by the shaft to.

It should be noted that after the bottles have been engaged by the teeth 32 and carried around into the oven, the carrier now being on a straight course, the sides of the teeth grip the bottles so as to retain them in spaced relation uniformly arranged. The gears 40 and 41 and the sprocket 34: are so proportioned that when a sufiicient number of bottles have been introduced, into the, chamber to extend across the same, the finger 43 will have reached the cam 4A. The conveyor belt is provided with blanks 50 be tween the series of teeth, so that while the bottles are being delivered from the teeth 32 on to the bed 51 no more bottles are being introduced into the chamber, thus there will be no bottles to interfere with the movement of the pusher 47.

After the bottles have been delivered to the movable bed, the latter will be moved forward a step aswill be understood by those skilled in the art, so that the last series of bottles-delivered to the bed will occupy the position shown at 52 in Figure 1, while the first series is being introduced into the chamber,

It will be noted that the transfer wheel 26 will deliver the bottles in spaced relation to the conveyor 0. They are fed by the conveyor C at a uniform rate to the conveyor D. When the blank 50 comes opposite the guide way) 31, there will be a slight accumulation of ottles, but the slight accumulationwill not cause sufiicient pressure to cause any injury to the bottles. The rate of travel of the conveyors C and ll) are so regulated that the bottles will be received by the latter and carried into the annealing chamber at practically the same rate that they are delivered by the conveyor C.

While T have shown and described what is now the preferred embodiment of my invention, it will be understood that various changes in the proportion and arrangement of the various parts may be made within the scope of the appended claims without departing from the spirit of the invention.

I claim as my invention:

1. The combination with an annealing oven, of means for conveying a row of bottlesfthereinto, including an endless belt conveyor having a series of fingers for grasping release the bottles successively and'conveying them into and along the bed of the oven, a pusher for delivering the series of bottles to the bed of the oven, means timed to operate said pusher when said series of bottles extend substantially across the oven, blanks on said conveyor between the series of grasping fingers, and timed to reach the wall of the oven simultaneously with the operation of said pusher whereby no bottles will be carried into the oven to interfere with the operation of the pusher. I

2. Thecombination with an annealing oven, of means for conveying, a row of botventing any bottles from being fed into the chamber while said pusher is being actuated. 3. The combination with an annealing oven, of means for conveying a row of bottles Y thereinto including an endless belt conveyor having a series of fingers for grasping the bottles successively and conveying them into.

and along the bed of the oven, sprocket wheels over which said conveyor travels, a pusher pivotally mounted to move transversely of the active lap of said conveyor, a rotatable .member operatively connected with one of the sprocket'wheels, a projecta ing finger carried thereby, a cam connected with said pusher and projecting into the path of said finger whereby said pusher will be rocked on its pivot at each revolution of said finger, vand a spring for restoring said pusher to normalposition.
